Abstract

See full text

Systems and methods to generate beneficial residual stresses in a material, clean, strip coatings from, or roughen surfaces by generating cavitation shock waves without damaging the surface of the material. Shock waves emanate through the target material from collapsing cavitation voids in and around a liquid jet to generate residual stresses without impinging the jet against the material, or by impinging the material at shallow angles, and without significantly damaging or deforming the surface of the target material.
